01 / PURPOSE-DRIVEN

Answers to the questions
buyers actually ask.

Every production decision should support fit, durability and a simpler path from order to installation.

01 / FIT

E-coat and powder finish

Surface preparation and coating work together to protect finished components.

02 / REAL USE

Seal contact and exposure

Glass, door interfaces and seals are checked as part of the complete assembly.

03 / PRODUCT

Vehicle-led development

Mounting, openings and usable space start with the target vehicle platform.

04 / SUPPLY

Structure and reinforcement

Forming and welding turn the cut panels into a consistent structural system.

05 / SHIPMENT

Sectional construction

Modular parts support packaging, transport and installation planning.

06 / AFTERCARE

Serviceable components

Hardware and seals are considered in the assembly and final checks.

02 / VEHICLE FIRST

Design begins with
the actual truck.

Fitment, access, weight and the way a canopy will be used guide the decisions before the first sheet is cut.

  • Vehicle-specific dimensions
  • Mounting and load paths
  • Door, glass and seal interfaces
  • Hardware access and serviceability

03 / SURFACE PROTECTION

A finish built in 3 layers with 80um-120um.

Cleaning, passivation and coating form a connected process before the canopy reaches final assembly.

UNDER THE FINISH

Protection begins before color.

Prepared components move through electrophoretic coating before the visible powder finish.

THE VISIBLE SURFACE

Made for everyday exposure.

Powder coating gives the finished parts a consistent appearance and an added protective layer.

04 / HOW IT IS MADE

Twelve clear production steps.

A visual path from design and fabrication through surface treatment, assembly and final checks.

  1. OFFROADCAP design team working on truck canopy drawings
    01

    Design

    Vehicle data, fit and function define the starting plan.

  2. Worker preparing aluminum canopy panels on a laser cutting table
    02

    Laser cutting

    Digital cutting produces the panel shapes and openings.

  3. Operator bending aluminum panels with a press brake
    03

    Bending

    Formed profiles set edges, angles and assembly geometry.

  4. Worker joining an aluminum truck canopy panel at the welding bench
    04

    Welding

    Prepared components become a connected structure.

  5. Technician grinding and polishing fabricated aluminum components
    05

    Grinding & polishing

    Edges and weld areas are refined for the next stage.

  6. Aluminum truck canopy panels being rinsed before surface treatment
    06

    Water / acid / alkali wash

    Rinsing and cleaning prepare the surface.

  7. Aluminum parts hanging in the shared surface pretreatment area
    07

    Passivation

    A pretreatment stage prepares the metal before coating.

  8. Metal components entering an electrophoretic coating bath
    08

    Electrophoretic coating

    E-coat adds a protective layer to prepared components.

  9. Black powder coated truck canopy frames hanging on an overhead production line
    09

    Powder coating

    The visible finish is applied to the coated parts.

  10. Worker checking a glass window in an aluminum canopy door
    10

    Glass assembly

    Window panels are fitted and aligned with the frame.

  11. Weather seal being fitted around a canopy door frame
    11

    Seal installation

    Sealing strips are installed around critical openings.

  12. Quality inspector checking an assembled canopy frame
    12

    Assembly & testing

    Fit, operation and completeness are checked before delivery.

05 / QUALITY GATES

Checked at four points.

In-process assembly and fit checks
  1. 01

    Incoming materials

    Check the inputs before production starts.

  2. 02

    Sheet metal fabrication

    Review cut, bend, weld and finish quality.

  3. 03

    Surface finishing

    Check the consistency of treated and coated parts.

  4. 04

    Assembly & dispatch

    Confirm fit, function and shipment completeness.

06 / COMPONENT DETAILS

Details that matter.

Small interfaces shape how a canopy feels, seals and functions in daily use.
